Changed wire, Now what
 

Hey,
I changed out the wire, still have a miss. Can anyone tell me how to check my coils. I was thinking one or all might be going bad. If you have any other ideas for me, please let me know.

Oh, my check engine light is still coming on and off. It will come on for a few minutes then go off again. I have replaced the gas cap, hoping that may be it. I tried to get the codes, but can't seem to get the reader to pick them up. If you have any ideas on that, please pass them on.

thanks for reading.
